LUBRICA'IING COMPOUND.

No Drawing.

I T 0 all whom it may concern Be it known that I. DANIEL. M. SoRENsoN, asubject of the King of Great Britaimresiding at Toronto. in the countyof York, in the Province of Ontario. Canada. have invented a certain newand useful Lubricating Compound, of which the following is aspecification.

In the application of oil for lubricating purposes in machinery andinternal combustion engines and-particularly in automobiles, it isinvariably found that after more or less extended use. and depending onthe presence of foreign matters therein and to a large extent also uponthe viscosity of the oil, such lubricants gradually deteriorate,

the oil globules break down and become gradually ineflicient for thepurposes of lubrication, and by reason thereof a frequent renewal of theoil is necessary.

Ordinary lubricants also tend to create a glaze upon surfaces which areintentionallybrought together for frictional purposes as, for example,the bringing of a brake band into contact .with a brake drumand rendersuch contact ineffective for the purposes of the contact. 1

My compound is intended to prevent such deterioration of the oillubricants as above mentioned and to prevent the formation of the glazeabove referred to.

In preparing my compound, I employ as a base or foundation an ordinaryneutral lubricating oil (such as defined in Vol. 2 of The AmericanPetroleum Industry, by Bacon and Hamor, published by McGraw- Hill BookCompany, Inc., at New York in 1916) having a body varying in viscosityfrom 200. to 300, Saybolt. at 100 F. To

such base I add not more than 10% in quantity of a pure soap produced bysaponifying fish, vegetable, or animal, oil

lubricating oils.

Specification of Letters Patent. Patented A 25, 1922,

Application filed July 11,

1921. Serial No. 483,997.-

the manner above set forth, does not deteriorate or break down under theinfluence of heat of .ordinary intensity generated by moving surfaces incontact, as do ordinary It creates and maintains a lubricating filmbetween the frictional surfaces and. in the case of automobile'engines.this results in increase-dmileage per gallon of fuel gasoline. Thecompound not being injuriously affected and carbonized by heatQthe partsto which it is applied will not become carbonized, as is the case whereordinary lubricants are empl'oyed. Furthermore, when used uponfrictional surfaces which are not continuously in Contact. but which arebrought together at irregulanintervals, my compounddoes not form-a hardglazed deposit thereon. as is the case with ordiriary lubricating oils.but creates a soft film or surfacing which acts as a cushion between thetwo contiguous surfaces and prevents them from slipping.

The process of treating the brake bands to prevent the formation of aglazed deposit forms the subject matter of my copending I claim:

1. A lubricating compound particularly useful for preventing theformation of hard glazed surfaces on friction bands consisting of a baseof neutral oil having an ammonia soap mingled therewith.

2. A lubricating compound particularly useful for preventing theformation of hard, glazed surfaces on friction bands consisting of abase of mineral oil having a viscosity of from 200 to 300 andhaving anammonia soap mingled therewith.

3. A lubricating compound particularly useful for preventing theformation of hard glazed surfaces on friction bands consistmg of a baseof mineral oil'having a viscosltv of from 200 to 300 and having mingledtherewith not more than ten per cent of an ammonia soap.
